Her three-year-old son Omar Omran tragically suffered fatal stab wounds to his abdomen, legs and chest, and died at least two hours before medics could get to him.

Al Adheem was treated at St James’s Hospital in Dublin after her operation on Monday night.

The Gardai believe little Omar had been dead for several hours before the emergency services were called at around 7pm on Monday. Paramedics were dispatched because the caller apparently said Omar had suffered a heart attack or seizure.

She is separated from her husband Khalid Omran, Omar’s father, who is also a doctor. He was told late on Monday night of the tragic death of his son.

A Garda spokesman said: ‘Gardai investigating the homicide of an infant child that occurred on Monday evening, July 10 2017, have arrested a woman (early 40s) this morning in Dublin.

‘The arrested woman is currently detained at Crumlin Garda Station under Section 4 of the Criminal Justice Act, 1984.’

The Irish Mirror reported that the woman arrested was Al Adheem. Detectives had been waiting for doctors to give them the go-ahead to interview her.
